Using Statement & Catch

[Fred Chateau]

To catch an exception associated with resources within a Using block, does
the Catch block go within the scope of the Using block or following it?

If within the scope of the Using block, what about nested Using statements?
Will a Catch block in the innermost Using block catch all exceptions?

Depends on what you want. If you put it inside the using block, it
will not catch exceptions thrown by the Dispose method. If you put a
try/catch around the using block, the resource variable will be out of
scope and not usable from the catch block.

Never mind...

I don't think you can use a Catch statement without a corresponding Try
statement, or at least Intellisense wouldn't accept it without one.

Very secure answered.
